  • Servidor De Correo X Ubuntu
    UNIVERSIDAD NACIONAL DEL CAAGUAZÚ FACULTAD DE CIENCIAS Y TECNOLOGÍAS Servidor de Correo X Ubuntu Responsables Marcelo Abrahan Acuña Santander Mario Manuel Moreno González Profesor: Ing. Héctor Estigarribia Ingeniería en Informática Coronel Oviedo -2016- Resumen Un servidor de correo es una aplicación informática ubicada en una página web en internet cuya función es parecida al Correo postal solo que en este caso los correos (otras veces llamados mensajes) que circulan, lo hacen a través de nuestras Redes de transmisión de datos y a diferencia del correo postal, por este medio solo se pueden enviar adjuntos de ficheros de cualquier extensión y no bultos o paquetes al viajar la información en formato electrónico. Montar un servidor de correo electrónico a base de GNU/Linux y software libre está al alcance de cualquiera, pero mientras que para el usuario corriente no compensa el esfuerzo, en el ámbito de la empresa sí es una práctica extendida por razones de privacidad y control de la información. Para montar un servidor de correo electrónico son imprescindibles diferentes elementos entre los que destaca el propio software que hará las veces de “mensajero”, lo que técnicamente se denomina como Mail Transfer Agent (MTA) o agente de transporte de correo en español. Y como no podía ser de otra forma, son varias las alternativas disponibles en el mundo del Open Source. Por eso ofrecemos un somero repaso a alguna de las más populares. Palabras clave: Servidor de Correo, Correo postal, Redes de transmisión de Datos, Control de Información, Software, Agente de transporte de Correo, Open Source. Abstract A mail server is a computer application located on a web page on the internet whose function is similar to the Post only that in this case the mails (sometimes called messages) that circulate, they do it through our Data transmission networks and Unlike postal mail, by this means only attachments of files of any extension can be sent and not packages or packages when traveling the information in electronic format.

  • Model Checking an Entire Linux Distribution for Security Violations
    Model Checking An Entire Linux Distribution for Security Violations by Benjamin W. Schwarz Research Project Submitted to the Department of Electrical Engineering and Computer Sciences, University of California at Berkeley, in partial satisfaction of the requirements for the degree of Master of Science, Plan II. Approval for the Report and Comprehensive Examination: Committee: David Wagner Research Advisor (Date) * * * * * * * Doug Tygar Second Reader (Date) Abstract Software model checking has become a popular tool for verifying pro- grams’ behavior. Recent results suggest that it is viable for finding and erad- icating security bugs quickly. However, even state-of-the-art model checkers are limited in use when they report an overwhelming number of false positives, or when their lengthy running time dwarfs other software development pro- cesses. In this paper we report our experiences with software model checking for security properties on an extremely large scale—an entire Linux distribu- tion consisting of 839 packages and 60 million lines of code. To date, we have discovered 108 exploitable bugs. Our results indicate that model checking can be both a feasible and integral part of the software development process. 2 Contents 1 Introduction 5 2 The MOPS Model Checker 6 2.1 Specification of Security Properties . 7 2.2 Scalability . 8 2.3 Error Reporting . 8 2.4 Efficient Model Checking with Pattern Variables . 9 2.4.1 Current implementation . 9 2.4.2 More Efficient Algorithms . 10 2.5 User Interface for Error Reporting . 11 2.6 Resource Usage . 12 3 Checking Security Properties 12 3.1 TOCTTOU . 13 3.2 A Standard File Descriptor Attack .

  • Sending and Reading Email
    Sending and Reading Email Get familiar with mailx, alpine, mutt, and mail. Creating a Signature file Automatically forwarding incoming messages Announcing an absence with vocation Configuring and managing email with procmail Using the Email An email message is identified by a sender and a receipt, both of which appear as headers in the message. mailx is a mail user agent for moving mails between users on the same host. Depending upon whether both sender and receipt are on the same host, an email address can take the following forms: 1. henry – user henry is on the same host 2. henry@saturn – henry is on a different host 3. [email protected] –henryis on the internet Internet Email Handling (1/3) Internet mail handling requires the works of at least three agencies: 1. Mail user agent –for reading the mailbox and sending mail, like mailx and pine. 2. Mail transport agent –for transporting mail between machines 3. Mail delivery agent –for delivering mail to the recipients’ mailboxes. MUA reads incoming mail from the mailbox and hands over outgoing mail to the MTA. MTA sends and receives mail. At the sending end, it identifies the recipient’s address and delivers the message directly to the MTA at the other end. At the receiving end, the MTA passes on mail to MDA. Internet Email Handling (2/3) MTA’s sending and receiving functions are handled universally by the simple mail transfer protocol (SMTP). The MTA doesn’t deliver mail. MDA does the delivery, like procmail. If the user’s host connects to the mail server intermittently, the user typically uses his ISP’s facilities to handle his mail.

  • Linux Network Administrators Guide Remote Systems
    Chapter 16. ManagingTaylor UUCP UUCP was designed in the late seventies by Mike Lesk at AT&T Bell Laboratories to provide a simple dialup network over public telephone lines. Despite the popularity of dialup PPP and SLIP connections to the Internet, many people who want to have email and Usenet News on their home machine still use UUCP because it is often cheaper, especially in countries where Internet users have to pay by the minute for local telephone calls, or where they do not have a local ISP and must pay long distance toll rates to connect. Although there are many implementations of UUCP running on a wide variety of hardware platforms and operating systems, overall, they are highly compatible. However, as with most software that has somehow become standard over the years, there is no UUCP that one would call the UUCP. It has undergone a steady evolution since the first version was implemented in 1976. Currently, there are two major species that differ mainly in their hardware support and configuration. Of these two, various implementations exist, each varying slightly from its siblings. One species is known as Version 2 UUCP, which dates back to a 1977 implementation by Mike Lesk, David A. Novitz, and Greg Chesson. Although it is fairly old, it is still frequently used. Recent implementations of Version 2 provide much of the comfort that the newer UUCP species do. The second species was developed in 1983 and is commonly referred to as BNU (Basic Networking Utilities) or HoneyDanBer UUCP. The latter name is derived from the authors' names (P.
